One of the core talents for tech characters, Sabotage, at its most basic, is used to stop an enemy from firing at you. This is useful on all gun-carrying opponents but especially more heavy-duty enemies like Geth Colossi or Geth Armatures if you are fighting them on foot, to kill their Siege Pulse; turrets, to stop them firing rockets at you; or snipers, to allow you to move freely out in the open.

However, Sabotage works specifically by overheating weapons, meaning it can be used on other targets too. Hitting containment cells or fuel tanks with Sabotage will cause them to explode, causing environmental damage and, in some areas, starting a massive chain reaction. On the down side, this means you need to be careful if you hit a nearby enemy with Sabotage while standing near anything explosive. Using Sabotage will also place a tech proximity mine.

Some enemies, like Geth Hoppers, also use Sabotage against you, rendering your weapon useless. In this event, either switch to an alternate weapon, use your biotics or tech talents, or take cover until your primary weapon has recovered.
